Chemical composition and acetylcholinesterase inhibitory activity of essential oils of Myrceugenia myrcioides (Cambess.) O. Berg and Eugenia riedeliana O. Berg, Myrtaceae
The chemical composition of volatile oils from two Myrtaceae species, Myrceugenia myrcioides and Eugenia riedeliana, both native from the Brazilian Atlantic Rain Forest, was analyzed by GC-MS. Acetylcholinesterase inhibitory activity was colorimetrically evaluated for these oils. For M. myrcioides, monoterpene hydrocarbons represented the major class in the volatile oil, with α-pinene as the mo...
متن کاملChemical Characterization and in Vitro Antibacterial Activity of Myrcianthes hallii (O. Berg) McVaugh (Myrtaceae), a Traditional Plant Growing in Ecuador
Myrcianthes hallii (O. Berg) McVaugh (Myrtaceae) is a plant native to Ecuador, traditionally used for its antiseptic properties. The composition of the hydro-methanolic extract of this plant was determined by submitting it to ultra-high performance liquid chromatography (UHPLC) hyphenated to heated-electrospray ionization mass spectrometry and UV detection. The presence of antimicrobial compone...
متن کاملAntioxidant and Antihyperlipidemic Effects of Campomanesia adamantium O. Berg Root
Campomanesia adamantium O. Berg, popularly known as guavira, has been used in Brazilian traditional medicine for reduction of serum lipid. The present study was carried out to investigate the antioxidant and antihyperlipidemic effects of Campomanesia adamantium root aqueous extract (ExCA). Phenolic compounds were quantified in the ExCA and gallic and ellagic acids were identified by HPLC. ExCA ...
متن کاملPhytotoxic potential of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg (Myrtaceae).
The loss of leaves by plant species found in the Cerrado (Brazilian savanna) is an energetically expensive process due to adverse environmental conditions and predation by herbivory. The mature leaves have adaptations which minimize these events. However, the young individuals lack these structures and produce high leaf concentrations of secondary metabolites as a form of protection. These comp...

to test whether termites of the Cryptotermes domesticus species might be able to discriminate between different sizes of wood. The team constructed experiments that presented termites with blocks of wood with a standard crosssectional diameter of 20x20 mm but of either 20 mm or 160 mm length. The insects were placed in a gap between the two faces of the timber blocks so that they were not able ...
